MEASURING DEVICE.

Specification of Letters Patent.

Application filed December 4, 1907.

Patented April 28, 1908.

Serial No. 405,076.

To all whom it may concern:

Be it known that 1, ROBERT LAUFER, a citizen of the United States,residing at East Greenville, in the county of Montgomery and State ofPennsylvania, have invented new and useful Improvements in MeasuringDevices, of which the following is a specification.

This invention relates to a measuring device intended primarily for usein connection with looms for measuring, in yards or other suitableunits, the ribbon, cloth or other fabric produced by the loom, and whilebeing particularly useful in this relation, it is to be understood thatthe invention is suitable for other uses.

The invention has for one of its objects to improve and simplify theconstruction and operation of measuring apparatus of this c aracter soas to be comparatively easy and inexpensive to manufacture, eflicient inuse, and possessing great durability.

A further object of the invention is the rovision of a simple andimproved mountmg for the device whereby it can be applied to a loom indifferent positions, according to the requirements of the given case,the device being in the nature of an attachment whereby it can be placedover or under the uide roll on which the ribbon or other Fabric runs.

Another object of the invention is to provide a measuring deviceincluding means for enabling the hands of the indicating mechanism torotate in the pro er direction irrespective of the direction 0 rotationof the contact roller of the device, so that the guide roll of the loomover which the ribbon passes can rotate in either direction.

With these and other objects in view, as-

will appear as the description proceeds, the invention comprises thevarious novel features of construction and arrangement of arts whichwill be more fully described hereinafter and set forth withparticularity in the claims appended hereto.

1n the accompanying drawings, which illustrate one of the embodiments ofthe invention, Figure 1 is a side view of the measuringdevicei Fig. 2'is a plan view thereof. Fig. 3 is a horizontal section on line 33 Fig.4, with parts in elevation. Fig. 4 is a vertical section through thecasing of the device. Fig. 5 is a fragmentary sectional view on line 55,Fig. 4, with parts in elevation. Fig. 6 is a fragmentary sectional viewshowing the hand-carrying arbor of the indicating mechanism and attachedparts. Fig. 7 is a sectional view on line 77, Fig. 2. Fig. 8 is asimilar view showing the parts in a difierent position. Figs. 9 and 10are views illustrating two different ways of using the device on a loom.

Similar reference characters are employed to designate correspondingparts throughout the several views.

Referring to the drawings, A designates the casing of the device whichis provided at its top with a glass or other transparent face 1 throughwhich is exposed a suitably graduated dial 2, and the hands 3 and LExtending from one side and connected with the casing is a tubularextension B from which project parallel arms 5 that are apertured forreceiving the bolt 6 that forms the axle of the contact wheel or roller7, which is adapted to bear against the ribbon or other fabric to bemeasured, or to bear against a roll over which the ribbon asses. Fromthe side of the casing op osite to the extension B extend arms 8 t atare apertured to receive the bolts 9 which contitutes a pintle forconnecting the arms with the yoke 10 of the supporting structure ormounting of the device. For yieldingly holding the contact wheel 7 inengagement with the ribbon or guide roll therefor, a spring 11 isarranged between the yoke 10 and casing of the device, the spring inthepresent instance consisting of a Ushaped portion 12 disposed underthe casing with its extremities coiled at 13 around the pintle and itsterminals bent under the cars 14 of the yoke, the torsional eflect ofthe coils 13 serving to urge the casing A and attached parts upwardly.The yoke is provided with vertical and horizontal threaded openings 15and 16, and screwing into either one of these openings, according to themanner in which the device is to be applied to the loom, is a clampingrod 18.

As shown in Figs. 9 and 10, the threaded I operates with a secondclamping jaw 21 to firmly secure the device to a suitable part of theframe of the loom. On the jaw 21 is a screw 22 for tightening orloosening the grip of the jaws.

In Fig. 9, the measuring device is mounted on the loom in such aposition that the contact wheel 7 bears upon the guide roll 23 overwhich the ribbon or other fabric 24 passes before being wound into abolt. C designates a portion of the frame of the loom on which the roll23 is supported and the ribbon is guided to the roll over the glassshaft or roll 25. The mounting for the casing A is clamped to a crossbar26 of the loom at a point in front of the roll 23, and the spring 11 isremoved so that the weight of the casing A and attached parts will besufficient to maintain the wheel 7 in proper relation with the roll 23.

When the device is used as shown in Fig. 9, the extremity of the screw18 is screwed into the o ening 16, as shown in Fig. 8, and the yoke 1sfirmly held in position by the clamping nut 17 of the screw being jammedagainst the said head. The jaws 20 and 21 are then adjusted so as toembrace the bar 26 and the screw 22 is then turned in a direction toengage the bar 26 on one side, while the jaw 20 engages it at theopposite side. Instead of engaging the screw in the opening 16, as shownin Figs. 8 and 9, it can be engaged in the opening 15, as shown in Fig.7, and when in this latter position, the spring 12 is not under as greata tension as when the parts are in the position shown in thefirstmentioned figures.

In Fig. 10, the ribbon 24 is run. approximately two-thirds around theroll 23 and thence over a cooperating guide roll 27 supported on a pairof spring members 28 that urge the roll 27 toward the roll 23, one ofsuch members being shown in the figure. The measuring device is mountedon the frame of the loom in a position under the guide roll 23 and thewheel 7 is held in contact with the latter by reason of the spring.

11. The mounting for the casing A is clamped to the horizontal beam 29of the loom frame. The jaw 20 engages one side of the beam 29 and thescrew 22 binds against the opposite side, with the rod 18 disposed overthe beam in such position that the head 15 bears on the to surface ofthe beam. It will thus be seen t iat as the ribbon is drawn over theroll 23, the wheel 7 will be rotated and caused to actuate theindicating mechanism of the measuring device.

With the device in the position shown in Fig. 10, the yoke 18 isadjacent the middle of the screw so that the yoke will bear on the topof the beam 29 and the clamping jaws 20 and 21 are disposed at oppositesides of the said yoke so as toengage the front and rear sides of thebeam. yVhen the jaws are adting the hands to be returned to zeroposition. On the arbor is loosely mounted a gear wheel 36 that mesheswith a pinion 37 on the pivot 38 secured to the plate 32', and connectedwith the pinion 37 is a gear wheel 39 that meshes with a pinion 40 onthe arbor. These pinions and gears constitute a speedreducing mechanismwhereby the rotation of the arbor 30 will cause the hand 4 to turn oneunit while the hand 3 makes a complete revolution, it being understoodthat the sleeve 30 to which the hand 4 is attached is rigidly connectedwith the gear wheel 36. Interposed between the plate 32 and. gear wheel36 is a spacing washer 41, and on the lower end of the arbor is a largegear wheel 42 which receives motion from the contact wheel 7 through asuitable mechanism.

Secured to the contact wheel 7 is a toothed wheel 43 that meshes with asmaller toothed wheel 44 on the horizontal worm-carrying shaft 45 thatis disposed within the extension B of the casing. On the shaft 45 is aworm. 46 that meshes with a worm wheel 47 on the vertical shaft 48, andon the lower end of this latter shaft is a gear 49 which transmitsmotion to the large gear wheel 42 through a reversing mechanism. Thismechanism comprises an oscillatory plate 50, Fig. 5, that pivots on thearbor 30 at the lower end thereof, and on this plate are pinions 51 42,the pinions being so arranged that when the pinion 51 is in mesh withthe gear wheel 49, the arbor will be turned in one direction, and turnedin the opposite direction when the pinion 52 is driven by the pinion 53by being thrown into mesh with the gear wheel 49, the pinion 53 beingmounted on the plate 50 and arranged permanently in mesh with the pinion52. On the plate 50'is a downwardly-extending threaded stud 54 thatpasses through a slot 55 in the bottom plate 34 of the casing, and onthe stud is a clamping nut 56 which is adapted to be screwed homeagainst the bottom plate 34 so as to clamp the oscillatory plate 50 infixed posi-' tion on the top of the bottom plate so as to hold eitherthe pinion 51 or 53 in mesh with the gear wheel 49. By providing thisreversing mechanism, the measuring device can be adjusted for operatingin connection with a guide roll for the ribbon, irrespective of whetherthe said guide roll rotates in a clockwise or anti-clockwise direction,it bein understood that the arbor must rotate on y in one direction.

In justec in position, as before explained, so that the contact wheel 7will be in engagement with the cloth to be measured. The movement of thecloth causes the contact wheel to rotate, and the gear wheels 43 and 44transmit motion from the contact wheel to the worm shaft 45. The worm 46in turn rotates the shaft 48 by the worm wheel 47 meshing with the saidworm and the gear 49 on the shaft 48, by meshing with either pinion 51or 53, transmits motion to the wheel 42 on the hand-carrying shaft orarbor 30. As the shaft 30 is turned, the quick-moving hand 3 turns withit, and by means of the intermeshing pinion 40 and gear wheel 39, andthe intermeshing pinion 37 and gear wheel 36, the sleeve 31 carrying theslowmoving hand 4 is turned so that by the position of the hands withrespect to the dial, the

. number ofyards of cloth can be readily ascertained.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the apparatuswhich I now consider to be the best embodiment thereof, I desire to haveit understood that the a paratus shown is merely illustrative, and tliatsuch changes may be made when desiredas are within the scope of theclaims.
